I really liked the TV show La Femme Nikita from a long time ago (I haven't seen the new version). The show selected really obscure bands - at least, as far as my untrained ears were concerned. It really opened up my enjoyment of a whole group of bands and songs I never would've heard of otherwise: Mandalay (Please), Hooverphonic (This Strange Effect), and Mono (Silicone).

(Other groups I found through LFN were Afro-Celt Sound System, Morcheeba and Morphine.)

There was this one episode where Michael and Nikita stayed in a log cabin in the woods and put on a record. The LP was of Fracoise Hardy singing Ma Jeunesse Fout Le Camp (translation: my youth is slipping away).

The lyrics are here... so wistful and sad. It was the first time I realized that I love sad music sung in French.

Anyway enough about my random musical interests. Do you listen to music from TV soundtracks? If so, let us know what shows and songs have piqued your interest!
